- a 1000-ml reaction vessel equipped with a baffle was charged with 55 g of a 6% by weight aqueous sodium carbonate solution prepared in Synthesis Example 1, 51.04 g of an aqueous sodium aluminate solution having a water content of 50% by weight and 25 g of ethanol, and a reaction was allowed to proceed at 40°C over a period of 20 minutes under vigorous stirring while dropwise adding 268.5 g of an aqueous JIS No. 3 sodium silicate solution which was prepared by diluting JIS No. 3 sodium silicate with water twice as much as the sodium silicate and 0.5 g of calcium chloride dihydrate. The pH value was adjusted to 11 with citric acid throughout the reaction. After the completion of the reaction, the system was aged at 40°C for 30 minutes.
- the obtained powder was found to comprise 29.3% by weight of Al2O3, 52.2% by weight of SiO2, 17.7% by weight of Na2O and 0.8% by weight of CaO (0.99Na2O ⁇ 0.05CaO ⁇ Al2O3 ⁇ 3.03SiO2).
- the Ca ion scavenging capacity and oil absorbability thereof were 164 mg CaCO3/g and 310 ml/100 g, respectively.
- a 5% dispersion of the powder had a pH value of 10.3, and the solubility of the powder in 100 ml of a 2 wt.% aqueous NaOH solution was 0.07 g.
- An agitation tumbling granulator (a Lödige mixer) was charged with 3% by weight of a sodium salt of a beef tallow fatty acid, a crystalline layer sodium silicate (b) [Na-SKS-6 (manufactured by Hoechst); particle diameter: 50 to 150 ⁇ m; cation exchange capacity: 280 mg CaCO3/g], the amorphous aluminosilicate (c') produced in Synthesis Examples 1 or 2, a zeolite (e) and a salt in respective amounts specified in Table 5 and 0.5% by weight of a fluorescent dye.
- a liquid nonionic surfactant (a) [a synthetic alcohol (C12 ⁇ 14) ethoxylate having a melting point of 15°C, an average number of moles of added ethylene oxide of 7 and a number of carbon atoms of alcohol of 12 to 14] in an amount specified in Table 5 was gradually introduced into the mixer, and then 2% by weight of a melt of a polyethylene glycol (d) having a weight average molecular weight of 8000 and further 0.5% by weight of an enzyme (0.3% by weight of protease and 0.2% by weight of cellulase), 0.5% by weight of a perfume and 2% by weight of water were added thereto and mixed with each other to provide a detergent product having the composition given in Table 5.
- a synthetic alcohol (C12 ⁇ 14) ethoxylate having a melting point of 15°C, an average number of moles of added ethylene oxide of 7 and a number of carbon atoms of alcohol of 12 to 14 was gradually introduced into the mixer, and then 2% by weight of a melt of a
